Meanwhile, it has been reported that Katy is taking acting lessons in order to pursue a career in television.

According to the Daily Star, Katy is keen to land a role in a sitcom.

"Despite her pop success she knows her music career won't last for ever. And as she found out with Russell, all that touring isn't good for maintaining a relationship," a source said. "She'd love to be in a sit-com."

Katy is currently enjoying a break from music following the promotion of her recent concert film, Part Of Me: 3D.
